INFORMATION
When checking the power wheelchair‘s batteries, make
sure the power wheelchair is standing on level ground.
INFORMATION
Before doing any maintenance work on the batteries,
please read the battery manufacturer‘s warnings thor-
oughly!
INFORMATION
The liquid level in the batteries must be checked on a
monthly basis and be topped up with distilled water if re-
quired.
The standard version of the B400 power wheelchair in-
cludes two 50 Ah/12 V wet cell (low-maintenance) batteries.
The batteries are located under the seat of the power wheel-
chair.
To check the battery, proceed as follows:
1. The seat bottom of the wheelchair must be removed for
maintenance work and for mounting/removing the
batteries.
2. Remove battery cover. Once the cover has been re-
moved, you have free access to the batteries (see
g. 17).
3. Unscrew the caps (see arrow, g. 17) of the individual
chambers by using a large screwdriver. You will be
able to see the battery’s liquid level on the acid level
markings.
4. If the liquid is below this marking, top up with distilled
water.
5. Replace the battery cover and reinsert and attach the
seat bottom.
Maintenance-free lead gel batteries can be used as an
alternative.
See section 6.3.4 for battery capacity display on the control
panel.
